HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 277,425, dated May 8, 1888.

Applicationl filed January 17,1883. (No model.l

,To all whom it may concern:

Be it known that I, GEORGE WV. PATTER- SON, a citizen of the United States, residing in the city and county ot' Philadelphia, State 'of Pennsylvania, have invented a new and useful Improvement in Attaching Wheels to Axles, which improvementis fully set forth in the following specilieation and accompanying drawings, in which- Figure 1 is an end view of a wheel hub and axle attached according to my invention. Fig. 2 is alongitudinal sectionthereof. Fig. 3 is a side elevation thereof, partly sectional. Fig. 4 is a side elevation, partly sectional, ofa modil tication.

Similar letters ot' reference indicate corresponding parts in the several figures.

My invention consists of an improved method of attaching a wheel to its axle, whereby 2o it can be readily applied to and removed therefrom. For thispurpose I secure to the end ofthe hub ofthe wheel a casting or stock, which has on its outer face a groove or way, within which are fitted two bolts, which are adapted to engage at opposite places with the axle, so that the wheel and axle are securely connected, and the bolts may be readily separated, to permit the disengagement ot' the wheel and axle by a toolor implement applied 3o through the band ofthe wheel, all as will be hereinafter fully set forth.

Referring to the drawings, A represents the hub of avehiolewheel, and B the axle thereof, which latterl has a conical or pointed head, a,

and adjacent thereto a neck, b.

C represents a cylindrical casting or stock, which is screwed or otherwise secured to the outer end ot' the hub, according with said end and circumscribed by the band D of the hub.

4o In the outer face of said stock C is a groove or way, E, which extends at a right angle to the axle, and contains two sliding bolts, F, arranged end to end, the inner end of each'having at its center a semicylindrical recess, c, to

receive the neck b oi the axle B, the sides of the way and bolts being of dovetailed form. The bolts are hollow in the direction of their length, and within the hollow or opening of each boltis a spring, G, which also rests against 4the band D, or a band, D', which is iitted par- 5o tially or entirely around the stock C, so as to form an abutment or bearing for the spring', the two springs serving to force the bolts F toward each other and the axle. The bandD is shown in Figs. l and 2 and removed in 55 Figs. 3 and 4, being secured to the stock C, and preventing` displacement ofthe springs when the band D is removed.

` It will be seen that when the axle is within the hub and one moved toward the other the 6c ,conical head at, coming in contact with the walls of the recesses c at the rear thereof, separates the bolts until the latter clear said head c, the bolts then springing into the neck b, and serving to connect the wheel and axle in a convenient, secure, and reliable manner without the employment of a linchpin, nut,

or similar loose piece.

In order to disconnect the wheel from the axle, the bolts F require to be operated in op- 7o'.

posite direction, thus separating them and moving them from the neck of the axle, whereby the wheel may be readily withdrawn from the axle, or vice versa, the head of 'the axle readily passing through the space'created be- 7 5 tween the inner ends of the bolts by the sepl aration thereof.

In order to operate both bolts simultaneously, I form on the outer face of each bolt y one or more lugs or openings,f, and employ a 8o pair of tongs, the jaws or ends of which may be tted to said lugs or openings, so that by closing the handles ofthe tongs thejaws separate and move the bolts in opposite directions. p

It will also be seen that, as the stoel; is firmly secured to the hub, the tool or implement to openu or separate the bolts may be inserted through vthe end of the band, and that said band is similar to the band usually attached 9o to a hub. Furthermore, while the stock and bolts are dovetailed or tongued and grooved, said bolts retain their places in the groove or A way E, and are prevented from outward dis placement. 'The two bolts, being placed end 9 5 to end and having coincident recesses, close fully around the axle back of the head a, and `prevent dirt, Ste., entering between the hub l l v 277,425

and axle, the two bolts, moreover,by means of around the back of the head of the axle, thus assisting to cause the wheel to run true on the axle. The back of the stock is formed with a tongue, C', which enters a mortise in the end ot' the hub, as in Fig. 3,'thus inter-l locking the stock and hub, said tongue and mortise being, however, dispensable, as in Fig. 4. The springs G enter the openings in the bolts, as has been stated, and against the springs on their outer ends bear plugs G, which also bear against the band, so that the outer ends of ther openings are closed by said plugs against the entrance of frost, rain, dirt, 85e., and the springs are accordingly guarded.

I am aware that it is not new to connect with a band a bearing-plate to which is fitted a bolt of annular form, which is adapted to engage with the neck of a wheel-axle, said bolt, however, yhaving but a small portion of its periphery bearing against the axle,a nd thus not bearing uniformly all around the axle. Ihe annular bolt is, moreover, not accessible from the outer end ot' the band, and when the band is removed said bolt and its spring lose their hold. Such construction also requires the employmentot' a screw passed through the band to disconnect the bolt from theY axle, and the bolt in its movement rubs against the end of the hub, all of which features are avoided byl my construction. The stock is a fixture of the hub, the bolts are reached from the end of the band, an ordinary band 1 is employed, the removal of the band does not disturb the stock .and bolts, and the bolts are in contact on their sides and back with the metal of the stock, and do not touch the wood of the hub. Again, as my bolts are arranged end to end, they come in contact, whereby the neck of the axle is relieved of friction of the bolts.

I am also aware that it is not new to employ two bolts as fastening devices for wheels and axles; but the same is so constructed in one case as to be opened by a scroll device at the front ofthe hub, and in other case to be held closed by a spring-key, which is connected with the bolts and opened by a button, the lever of which is at the front of the hub, such device and lever being dispensed with by my construction. A

Having thus fully described the construction, operation, and advantages of my invention, whatI claim as new, and desire to secure by Letters Patent, ist Y 1. In a wheel and axle attachment, astock secured to the wheel and formed with a groove or way, in combination with two bolts fitted in said groove end yto end, and having openingsfon their outer faces for the reception of the jaws ot'a pair of tongs, substantially Las and for the purpose set forth. f

2. A wheel andK axle attachment, consisting ot' a grooved stock, springs, and two hollow bolts, the latter containing Within them said springs, substantially as and for the purpose set forth.

3. A wheel and axle attachment consisting` y lof a grooved stock, two bolts, springs fitted in openings in said bolts, and plugs, which latter bear against the springs in the openings in the bolts and close the outer ends of said openings, substantially as and for the purpose set forth.

4. In a wheel and axle attachment, a grooved stock, bolts, and springs, in combination with an inner band, D', which is secured to said stock and inclosed by the band D of the wheel, substantially as and for the purpose set forth.
